May 15 (Reuters) - A sharp rise in jet fuel prices due to the U.S.-Israeli war on Iran has caused turmoil in the global aviation sector, prompting airlines to raise ticket prices and revise their financial outlooks.

Jet fuel prices jumped from a range of $85-90 a barrel to between $150-200 a barrel amid the war , in a sector where fuel accounts for up to a quarter of operating expenses.

Here are some of the precautionary measures taken by major airlines around the world:

Aegean Airlines

The Greek airline expects the suspension of flights to the Middle East and the sharp rise in fuel prices to have a "significant impact" on its first-quarter results.

AirAsiaX

Malaysia Airlines said it plans to suspend flights between Melbourne and Denpasar and between Adelaide and Denpasar from June 18 due to high fuel prices.

Company executives had previously said that the company had cut its flights by 10 percent and also imposed additional fuel charges of about 20 percent.

Air Canada

Canada's largest airline has put its full-year forecast on hold due to the turmoil in fuel prices.

The company had previously announced plans to cut four of its 38 daily flights to New York due to rising fuel prices.

Air China, China Southern Airlines, and regional Chinese airlines

Chinese airlines plan to raise fuel surcharges on domestic flights starting May 16. For domestic flights under 800 kilometers, the surcharge will increase from 30 to 90 yuan (US$4 to US$13). For longer domestic flights, the surcharge will rise from 50 to 170 yuan.

* Air France-KLM

The group expects a $2.4 billion increase in its fuel bill this year. It had previously revised its full-year operating capacity forecast downward from a projected growth of 3-5% to 2-4%.

The group had previously announced its intention to increase ticket prices for long-haul flights to cope with rising fuel costs, with ticket prices set to rise by 50 euros ($58) for each round trip.

On April 16, Dutch airline KLM, part of the group, said it would cancel 160 flights in Europe over the next month due to rising fuel costs.

Air India

Air India will temporarily reduce the number of its flights on several international routes between June and August.

Bloomberg News previously reported that the company explored the possibility of laying off some non-technical staff and reducing its flights by more than 20 percent over the next three months.

The company also said it would adjust fuel surcharges on domestic flights, switching from a fixed rate to a distance-based system. It added that fuel surcharges on international flights no longer compensated for the sharp rise in jet fuel prices.

Air New Zealand

Air New Zealand predicted its biggest annual pre-tax loss in four years and announced it would review its capital spending plans and aircraft delivery schedules to better align with demand and market conditions.

The airline raised ticket prices and tripled its capacity, and was among the first to announce significant fare increases when the conflict erupted. It warned of further capacity reductions if fuel prices continued to rise.

Air Transat

The Canadian airline said it plans to reduce its planned operating capacity by six percent from May to October of this year, with expectations of reduced flights to Europe and the Caribbean, while its flights to Cuba remain suspended until October.

* Acacia Air

The Indian company imposed additional fuel charges ranging from 199 to 1300 Indian rupees (between $2 and $14) on domestic and international flights.

The airline raised its checked baggage fees by $10 for each of the first two bags and $150 for the third checked bag on domestic and short-haul international flights. It also reduced the range of some benefits offered to economy class passengers.

* A.N.A. Holdings

The Japanese airline said that rising fuel prices would increase expenses by about 140 billion yen ($883 million) this year, but that hedging and cost-cutting measures are expected to limit the impact to about 60 billion yen. The company is considering imposing a fuel surcharge on domestic flights during the fiscal year beginning in April 2027.

Asiana Airlines

Newses reported that the South Korean airline plans to reduce its flights by 22 between April and July due to rising fuel costs.

The airline announced it will reduce capacity by approximately 3.5 percentage points compared to its original plan, along with raising checked baggage fees in an effort to offset higher jet fuel costs. The changes include a $10 increase for the first two bags and a $50 increase for the third.

The American airline cancelled all plans to increase service capacity scheduled for the second quarter and forecast lower profits than Wall Street expected.

EasyJet

The company warned of a larger pre-tax loss in the first half of the year, ranging between £540 million and £560 million ($721 million-$748 million), including £25 million in additional fuel costs in March.

Frontier Airlines

The Wall Street Journal reported that a group of low-cost U.S. airlines, including Frontier, submitted a $2.5 billion bailout request to the U.S. government. The report explained that this figure is based on projected increases in jet fuel costs this year compared to previous forecasts.

The company says it is revising its full-year forecast, as fuel prices have risen sharply since the forecast was issued.

Greater Bay Airlines

The Hong Kong-based company said it will raise fuel surcharges on most routes from April 1, while keeping fares for routes to mainland China and Japan unchanged.

Hong Kong Airlines

The company said it will raise fuel surcharges by up to 35 percent from March 12, with a sharp increase on flights between Hong Kong and the Maldives, Bangladesh and Nepal, where the surcharge will rise from HK$284 to HK$384 ($49).

* IAG Group

The group that owns British Airways said its annual profits would be lower than expected, as rising jet fuel prices and supply disruptions negatively impacted earnings more than anticipated.

The group had previously stated that it would raise ticket prices to keep pace with rising fuel costs, as it, despite hedging measures, was "not immune" to the wider repercussions of fluctuations in fuel prices.

Indigo

India's largest airline said it will impose fuel surcharges on domestic and international flights from March 14, including a charge of 900 rupees for flights to the Middle East and 2,300 rupees for flights to Europe.

In April, Lufthansa unveiled a new low-cost option called "Basic Economy" for short and medium-haul flights, under which free baggage will be limited to just one carry-on bag, which is a "laptop bag or small backpack".

The group had previously cancelled 20,000 short-haul flights from its schedule through October, noting that this equates to about 40,000 tons of jet fuel.

Pakistan International Airlines

The company said it would raise domestic flight ticket prices by $20 and international flight prices by up to $100, citing higher fuel surcharges.

Qantas

The Australian airline said it has postponed a previously planned A$150 million (US$106 million) share buyback and will raise its fuel cost estimates for the second half of 2026 to between A$3.1 billion and A$3.3 billion, compared with previous forecasts of A$2.5 billion.

Ryanair CEO Michael O'Leary warned that the company's profits could come under some pressure during the financial year ending in March 2027 if oil prices remain at high levels.

* S.A.S

The decision included applying these additional fees to bookings made on or after April 1st, with the fees taking effect on departing flights from May 1st.

Turkish Airlines said on April 10 that it had decided not to distribute any cash dividends from its 2025 net profits, citing its preference to retain profits to maintain cash flow.

* T.Y. Air

South Korea's low-cost airline said it plans to lay off a number of cabin crew members temporarily and without pay during May and June, as part of measures to cope with the fallout from the war in the Middle East.

United Airlines

Chief Executive Scott Kirby said that fares may need to rise by 15 to 20 percent to offset the sharp increase in fuel costs. The airline had already implemented five fare increases late in the first quarter, in addition to raising baggage fees, in what it said was beginning to compensate for the higher fuel costs.

The company predicted that its second-quarter and full-year earnings would fall short of Wall Street estimates, and said it expected to offset only 40 to 50 percent of the fuel price increase through ticket prices and other revenue measures in the second quarter, with that improving to 70 to 80 percent in the third quarter, and to 85 to 100 percent by the fourth quarter.
